Miami-Dade Mayor Says Screwworm Limited To 1 Stray Dog

The mayor of Miami-Dade County says he'll devote "whatever resources are necessary" to protect pets and livestock on Florida's mainland from screwworms.

State agriculture officials announced Monday that the parasite that eats the flesh of living animals had been found in a stray dog in Homestead. Since October, officials have been trying to keep a screwworm infestation in the Florida Keys from spreading beyond the island chain.

With the addition of five more cases Monday, Florida's total number of diagnoses of the mosquito-borne Zika virus topped 1,100, according to information posted online by the state Department of Health.

The total hit 1,103, including 124 infections involving pregnant women. Zika is particularly dangerous to pregnant women because it can cause severe birth defects.

Five new cases of locally transmitted Zika virus were reported in Florida on Monday, bringing the state's total overall number of individuals who acquired the disease from local mosquitoes to 146, according to information released Monday by the state Department of Health. Overall, there are 933 Zika cases in Florida.
